'To all whom it many concern."

,Be it known that 1-, WILLIAM L. THOMP- son, a citizen of the United States, residing at Highmore, in the county of Hyde, State of S'outhDakota. have invented certain new and useful Improvements in Insect-Traps;

and I do hereby declare the following to be a-ndexact description of the invention; such as will enable others skilled in the art to which it appertains to make and use the same.

This'invention relates to an improvement in fly traps.

The primary object to provide a device of this character which will be eilicient in practice, simple in construct-ion and economical to manufacture.

Vvith theabove and other objects in view the invention consists in, certain construe tions, combinations and arrangements of parts, clearly described in the following specification and clearly illustrated in the accompanying drawings.

In the draw1ngs:Figure l is a side elevationof the device, the trap being in an open position. Fig. 2 is a similar view the fly entrance being closed the inner valve or gate being shown in its open position. Fig. 3 is a detail sectional view the cylindrical casing-being removed. Fig. l is a. view showing the cylindrical member provided with a modified foruicf closure. Fig. 5 is a side elevation of a box which may be utilized to remove the flies from the'trap. Fig. 6 is a top plan view of the cylinder, Fig. 7 is adetail view of one ol' the guides shown in the modified form.

In the drawings, 10 designates a base member on which is positioned spaced sup ports 11. -Av supporting plate 12 rests on said supports, said plate 12 being provided with the central circular aperture 12. Arranged at equi-distant points adjacent the edge of said circular aperture and extending upwardly therefrom are su porting membore 13, 14, 15 and 16 which support the cylindeF-l'? formed of wire niesh,-a circular plate 18 forming a closure for said cylinder, said plate being supported by the end portions of the supports. The supporting plate 12 is spaced from the base 10 by the supports 11 said supports extending trans versely across the base forming openings 19 and 20 beneath the plate lflwhich may be closed byrmeans of a yoke 21 which is pivotally supported by one of the supports her 2 adapteu to form a The cylinder 17 has its lower end portion. secured to the surrounding wall of the ancr ture 12 and a conical member 23 of wire mesh is placed within the cylinder in has its lower end also secured to said plate w in the opening, while positioned on the top of the conica member 23 is an annular niemseat for a valve or gate 25, said annular member and said gate being hingcdly connected at the point A cable 27 is secured to said gate, sold cable extending through theplate 18 o r tlipulley 18 arranged on said plate, said cable being connected to the bar 21 cat the 31; the cable being of such length that Y gatewill be in an open position when a yoke 21 has been swung on its pivot to cl the entrances to the cylinder. It wi be noted that the gate is opened to. its full extent as soon as the entrance to the cylinder is closed. A rod 28 is connected to said gate, said rod extending through the plate 18. It willbe seen that by forcing this red within the cylinder thegatewill be close and the yokeswung on its pivotby means of the cable 27. I I

The trap is shown. in set position in Fig. 1 a suitable bait being placed on the-support beneath the conical member. The flies enter beneath the supporting plate and after a suiiicient number have entered, the yoke is forced down closing the entrance for the flies and opening the valve or gate. A suit able device such as the rod 29- within the conical member. said rod 1 provided with means which wi en is reciprocated drive. the flies throi i opening in the conical member to the u portion of the cylinder. After the entered the cylinder the trap may be on the stove or in an oven and the .o stroyed. When the trap is too large to be conveniently placed in an oven the box shown in Fig. 5 is utilizedsaid box being substantially rectangular and providcd with the so id base portion 30 andthe end walls 31, the base-portion 30 being formed with a central circular aperture 32 from which en'- tends a flange 33 said aperture being closed by the hingedly supported gate member 3a which is opened and closed through the medium of the rod 35 which extends through one of the end portions 31. In removing the flies from the cylinder the rectangular box positioned on the plate 18 the extending within an aperture 5 form-ed in Iilltl' is p ositioned said late, said aperture being normally closed by means of a slide 36. The fiies will enter the box when the in its open osition. A ter the same have entered the box said gate member is-closed and the box is removed from the cylinder, the box may then be placed in the oven to destroy the flies. Attention is called to the fact that the gate which is positioned within the cylinder is formed of an annular member which 'is covered with wire mesh,'

said wire mesh being formed at points adjacent the annular member with apertures so formed as to permit of the entrance of a fiy yet preventing the return of said fly,

thus permitting the insects to pass through ceive said extensions.

which enter guides 39, said guides being provided with elongated slots 40 which re- The guides are formed of metal, their end portions being bent to extend within the cylinder, the

guides extending beyond the cylinder and assisting in the support of the same. In this form the cable 28 is secured to one of the oiisets, said cable being adapted to move the band on the cylinder to close the opening beneath the same in the same manner as in the preferred form, the yoke being the equivalent of the band.

The many advantages of a tra constructed in this manner Wlll be clear y apparent as it will be seen that the insects may be conveniently removed from the trap.

ate member 34 is I claim 1. A fly trap consisting of a supporting base, supports transversely arrange on sai base, aplate mounted on said supports, said plate being spaced from said base, a yoke pivotally connected to one of said supports,

a cylinder formed of wire mesh, said cylinder being embraced by the edgeportion of a centrally arranged opening formed in said plate, the lower end of said cylinderbeing secured' to said plate, a conical exten sion within the cylinder and also secured to said plate, an annular member mounted at the mouth of said extension, a second annular member hingedly connected to the first mentioned member, said second memberv being covered with wire mesh, a cable secured to said second member, said cable passing through a plate adapted to form a closure for the upper end of said cylinder, the end portion of said cables being connected to said yoke, and a rod extending through said plate, said rod being connected to said second member to swing the same on its pivot.

2. A fly trap consisting of a base, a sup porting plate spaced from said base, a pivotally supported yoke, a cylinder formed of wire mesh, the lower portion of said cylinder being arranged within an opening formed in said plate, a cone also arranged within the opening and extended within th e 75 cylinder, an annular member arranged on said extension, a closure plvotallyr connected to said annular member, and means for opening said closure as .said yoke 1s swung on its pivot.

In testimony whereof, I aiiix my signature, in presence of two witnesses.-

WILLIAM L. THOMPSON.
